To all whom t may concern.'

Be it known that I, EDWARD B. JAooBsoN, a citizen of the United States,residing at Pittsfield, in the county of Berkshire and State ofMassachusetts, have invented certain new and useful Improvements inBushing-Removers, of which the following is a specication.

This invention relates to special hand tools, and, more particularly, toan implement for unseating and removing worn bushings requiringreplacement.

The primary obj ect of the invention is the provision of simple andeffective mechanism by which one of a pair of bushings seated inopposite ends of a tubular body of uniform bore may be readily removedwithout causing injury to its mounting or to the remaining bushing.Among the several advantages appertaining to the present implement arethe simplicity of its structure and application, which does not requirepreliminary adjustment or auxiliary attachments.

The novelty of the invention resides in the construction, combination,arrangement, and operation of the component parts, asl hereinafter'described andl shown.

Referring to the accompanying` drawings, which illustrate a preferredform of embodiment of the invention, Figure l is a side elevation of thedrifting tool with the lower ends arranged in the closed position, aportion of its length being shown in section to disclose the jointedconnection of the complementary parts; Fig. Q1, a bottom view of thesame; Fig. 3, a longitudinal sectional view of a spindle-body andbushings mounted therein, with the drifting tool partly introducedthrough one end; Fig. 4, a view similar to Fig. 8, showing the assembleddevice fully adjusted for operation within the spindle-body; and Fig. 5,a perspective view of one of the bushings normally mounted in thespindle-body.

The invention comprises a drifting tool and a separate detachableholder.

The drifting tool l constitutes the portion introduced into the spindlebody 21, and in process of manufacture is preferably constructed of asuitable length of round steel rod having a plane face 2 at its lowerend and a reduced extension 3 at its upper end for the support of adetachable holder 4. Said rod is divided lengthwise into twoSpecification of Letters Patent.

equal parts, designated as fingers, 5, 5, which are semifcircular incross-section and of uniform dimensions throughout their length. Thefingers 5, 5, are movably secured together at a point somewhat abovetheir middle by a fulcrum pin 6 extending through oppositely arrangedtransverse openings 7 7, and secured in position by heads 8, 8, providedat both ends and adapted to seat in corresponding enlargements of theopenings 7, 7 at their outer ends. The walls of the openings 7, 7,between the heads of the pin 6 are beveled to provide suitableclearances around the body of the pin for the purpose hereinafterrelated.

The fingers 5, 5, are bent inward at the point of attachment to providea predetermined permanent angular relation of the upperportion of eachfinger to its lower portion and in such manner as to preserve the planefaces of both portions, whereby, in spreading corresponding endsrelatively apart, the opposing faces of the opposite ends are broughtinto engagement throughout their length, and vice versa. Seated on theinner face of one of the fingers 5 preferably at a point above the pin 6is a stationary guide-pin 9 extending beyond the supporting finger andinto a recess 10' of appropriate size provided on the inner face of theopposite finger to serve as a guide-way for opposing lateral movement ofthe fingers on the pin 6 and hence toy maintain the fingers,` in truealinement with each other.

The clearances provided by the openings 7, 7, around the middle or bodyportion of the pin 6 permit the alternate spreading and closing actionof corresponding ends of the fingers necessary for introducing andwithdrawing the drifting tool into and from the spindle-body 2l.

The holder 4 is preferably constructed of a suitable length of round rodsimilar to the stock employed in the construction of the drifting tool'and is provided at its lower end with a recess or socket 11 adapted toreceive the reduced upper ends of the fingers 5, 5, when in closedposition and is of corresponding size. When mounted on the driftingtool, the holder` 4 operates as a securing member to hold the upper endsof the lingers 5, 5, in closed position and consequently to maintain thespread relation of the lower ends of the fingers.

to serve as a bearing face. To remove the bushings l23, 23, Which aresubject to rapid Wear and require frequent replacement, thedriftingltool 1 -isfinserted -inV one end of.' the l'spindle-body 21intheposition illustratedin Figs. l1,2, 1and 3,1the lower ends of thelin- [gers 5, 5, being in the closed position. lWhen inserted as yfar asthe inner end ofthe bushing'23 at the opposite end of the spindle--lbody 21, the lowerends of the fingers are spread; apart` to seat on therim at the inner end .of the bushin-gby pressing together the upper endsof 'the fingers 5, 5, assuming the position shownin 4. rl"he holder 'ilis then mounted, as shown, on the reduced extension to act as aclampffor the :fingers and as a-medium to which force may be applied tovdrive the bushing out. The implement is then removed by the reversal ofthese operations, 1when the remaining bushing maybe removed in the samemanner.

I claim: 1. vIn azhandtool, a pair of angular arms.
